PT-141 (Bremelanotide) — Central Sexual Function Research Peptide
PT-141, known generically as Bremelanotide, is a synthetic cyclic heptapeptide and melanocortin receptor agonist derived from Melanotan-2. Unlike erectile dysfunction compounds that work through vascular mechanisms, PT-141 activates MC4R receptors in the hypothalamus — directly engaging the CNS component of sexual arousal. It is the only FDA-approved peptide for HSDD (Hypoactive Sexual Desire Disorder) in females, providing an extraordinary research evidence base.

Reconstitution: Add 0.6% Acetic Acid first to dissolve the powder, then dilute with Bacteriostatic Water (BAC Water) or Sterile Water for your working solution. Store lyophilized vials at 2–8°C.
Key Research Areas
🔥 Central Sexual Arousal Mechanisms
PT-141 acts centrally rather than peripherally — bypassing the vascular mechanisms of PDE5 inhibitors to directly activate hypothalamic dopaminergic circuits. Research models demonstrate heightened sexual motivation, spontaneous erections, and lubrication responses independent of peripheral blood flow.
👩 Female Sexual Dysfunction Research
PT-141 holds FDA approval as Vyleesi for HSDD in premenopausal women — the only research-backed peptide compound with regulatory approval for female sexual dysfunction. Studies show significant improvements in desire, arousal, and satisfying sexual events.
👨 Male Erectile Function
Phase 2 research in male subjects demonstrated significant improvement in erectile function scores, including in men who were non-responsive to PDE5 inhibitors — opening a unique research avenue for refractory ED models.
🧠 Melanocortin CNS Pathway Research
PT-141 provides a precise research tool for studying the role of central melanocortin pathways in sexual behaviour, dopamine reward circuits, and hypothalamic regulation of desire.
